Application filed February 13, 1918. Serial No. 216,897.

T 0 (17110710722, if may concern Be it known that I, JOHN FRED GATES, acitizen of the United States, residing at Corcoran, in the county ofKings and State of California, have invented certain new and usefulImprovements in Pump Controls', of which the following is aspecification.

This invention is a pump control more particularly adapted for theremote control by the flow of water from an outlet, wherein use is madeof a movable member that is more or less flexibly connected with acut-out mechanism that cooperates with an indicating, device.

One object of the invention is to provide a control having its primaryoperating means so disposed that water or other fluid leaving an outletwill impinge against the same.

Another object of the invention isto pro vide a cut-out mechanism thatis adapted to be connected with the primary operative means, whichcut-out mechanism includes suitable devices and instrumentalities forautomatically opening an electric circuit.

Still another object of the invention is to provide an indicating meansthat is simultaneously operated with the circuit opening mechanism.

A further object of the invention is to provide the primary operativemeans with suitable devices to enable it to be operatively connectedwith an outlet such as a 21 still further object of the invention is toprovide a cut-out mechanism that employs a hooked arm that is pivotallymounted and which serves as a trip member for retaining and releasing aresilient element that is adapted to simultaneously close a circuitleading to an electric lamp, said resilient element operating anelectric'switch.

Broadly stated, the invention comprises a primary operative means whichis positioned at a remote point and includes a pivotally mounted gatethat is flexibly connected with a hooked member that serves as a tripand release, said primary operative means being detachably secured in apipe or other conduit so that the gate will be operated by fluid passingtherethrough. said hooked arm being pivotally mounted within a casing sothat one end thereof is adapted to cooperate with an engaging membersecured to the end of a resilient member which has its other end securedto' ed to control the flow of electricity in a connected circuit, and ablock so arranged that when the engaging member engages with the hookedarm said block will act as a stop therefor.

One practical form of construction and assembly will be described andillustrated in the accompanying rawings, in which Figure 1 is asectional view of the recep tacle showing the several operative featurescontained therein, and a disconnected side elevation of the end of apipe having the primary operative means connected thereon, and

Fig. 2 is a sectional view of the primary operative means, on the line22 of Fig. 1.

In the preferred embodiment about to be described a pipe 15 having aflange 16 is shown as the means for directing the flow of the water 17against the pivotally mounted gate 18. The primary operative means ismounted adjacent the end 16 of the pipe 15 by means of a short length ofpipe 19, having the flanges 20 and 21. These flanges 20 and 21 areprovided with alining holes through which are adapted to pass anysuitable securing means, such as bolts.

The gate 18 is mounted on the shaft 22 and is held thereon by means ofthe screws 23. In order that the gate may be secured to the shaft, oneend of the gate is provided with a passage adapted to receive the shafttherein.

The shaft 22 is rotatably mounted insuit able bearin s formed in-thebosses 24 and 25. These osses are preferably placed in alinement witheach other and offset relative to a diameter of the pipe 19. As shown inF1 2, the gate is approximately rectangufar in'shape, and when water isnot passing, it lies transversely of the pi 'e.

To operate the gate 18 from outsi e the pipe 19, the shaft 22 hasconnected to it, a

lever 26. This lever 26 has an eye 27 formed at one end so that it mayreceive the shaft 22. As this lever 26 should be firmly secured to theshaft 22 a set screw 28 is employed. This set screw passes through asuitably threaded hole formed in the lever so that it may the eye 27 andengage with the shaft 22. The drawings show the lever 26 positioned atright angles to the shaft 22 to lie in a plane parallel to the gate 18.The other end of the lever 26 may also be provided with an eye 29 topermit connection with the flexible element 30.

The flexible element 30 extends from the eye 29 and over a pulley 31that may depend from a suitable support indicated at 32. From thispulley 31 the element 30 passes through an opening 33 formed in the rearwall 34 of the casing or receptacle A. The element after passing throughthe opening 33 is adapted to pass over a suitably sup-' ported pulley35. The end of the element 30 is adapted to be secured in the eye 36formed in the end of the hooked arm generally indicated at 37. This armis pivotally mounted at 38. As shown the arm is curved with varyingdegrees of curvature upon each side of the pivot 38.

The arm 37 is composed of two portions indicated at 39 and 40. Theportion 40 is of such shape that it approximately forms one quarter ofthe circumference of a circle. The portion 40 may also serve as a trip.The free end of the portion 40 is preferably so shaped and formed thatit is adapted to cooperate with an eye 41 formed in an engaging member42.

The engaging member 42 is provided with two portions that extendoppositely from the eye 41. Each one of these portions is provided witha suitable hole adjacent its free end. The upper hole is adapted to havesecured in it a flexible element 43. This element 43 is adapted to passover a pulley 44 and have its other end suitably connected as at 45 withthe handle 46 of an electric switch 47. The switch 47 is adapted tocontrol the circuit indicated by the wires 48 and 49.

The lower hole of the other portion of the engaging member 42 is adaptedto be engaged by the end 50 of a spiral spring 51. As shown the spring51 has its lower end 52 connected with an eye 53 that may be suitablysecured or screwed into the lower wall 54 of the casing A. To cooperatewith the engaging member 42 there is provided a block 55 thatmay besecured to the wall of the receptacle in any suitable manner. As shownin' Fig. 1 this block is horizontally placed with one end abuttingagainst the rear wall 34. Its other end is so positioned that it willserve as a stop to prevent backward movement of the engaging member 42.

The spring 51 has at the point 56 its convolutions slightly separated toprovide for the insertion of a switch arm 57 pivotally mounted at 58 tothe block As shown the block 59 is substantially .L-shaped and may besecured to the back wall 34 in any suitable or customary manner. Theswitch arm is adapted to engage with a contact 60 as shown in Fig. 1.

Connected with the contact 60 is a conductor 61 forming one side of acircuit leading to an electric lamp indicated at 62. The other terminalof the lamp has connected to it a conductor 63 forming the other pait ofthe circuit. This conductor is connected at its other end with oneterminal of a source of electric energy indicated by the two dry cells64. The other terminal of the battery 64 has connected to it a conductor65 that has its other end connected with the block 59.

The eye 36 formed at the end of the arm 37 is adapted to be engaged withone end of a spring 66. The other end of this spring 66 is adapted toengage with any one of the hooks 67. These hooks may be mounted in ablock 68 if so desired, and the block may be secured to the wall 69 ofthe casing A. As shown the hooks 67 are preferably positioned at a pointbelow the pivot 38 and upon the opposite wall so as to providevariations in tension or pull upon the arm 37.

The receptacle or casing A may be formed of suitable material and ofsuch size and shape as will best adapt it to hold the various devices.As shown the casing is secured to a wall or other support B, by means ofthe brackets indicated at 70 and 71. These with the eye 41 of theengaging member the spring 51 will ordinarily hold the arm in position.This will permit the closing of the 'switch 47 and take the slack out ofthe element 43. The spring 66 will be placed under tension but notsufficiently to withdraw the curved end 40 from its. engagement with theeye 41. a

When the arm 37 is engaged with the eye 41 the element 30 will be insuch a position that the water flowing will impin e upon the gate 18,moving it upward as s own to the right in Fig. 1. This will hold the arm37 in position. As soon as the flow of water lessens until it finallyceases the gate 18 will drop to the vertical position which will permitthe spring 66 to pull the end 40 from engagement with the eye 41.

he release of the engaging means 42 by the curved portion 40 will permitthe spring 51 to retract which in doing so will pull on the element 43opening the switch 47 thus breaking the circuit which includes the wires48 and 49.- At thesame time the spring 51 in retracting will cause thepoint of separation 56 to move downward carrying with it the switch arm57.

As the arm 57 moves downward it breaks contact with the contact 60 andopens the circuit that includes the battery 64 and the lamp 62. The lamp62 will then be extinguished by the opening of the circuit.

Fig. 1 shows the primary operating means as being mounted in a shortsection of flanged pipe 19 so that the means may be inserted in theoutlet pipe at a suitable point. If desired, the length of pipe shown atthe right may be disconnected and the water will then flow freely fromthe flanged end 21 into a convenient receptacle.

What is claimed is:

1. A circuit controlling device including separate switch arms, anelastic coupling element adapted to. be connected to the switch arms andto be tensionably stretched upon the setting of the arms in apredetermined position, means for holding under given conditions, thecoupler element as stretched between the switch arms and means forreleasing the coupler element in an emergency whereby it relaxes andshifts the switches to another predetermined position.

2. A circuit controlling device including a. trip, a trip engagedmember, means for retaining the trip and member in mutual engagementunder given conditions, adjustable means for tensioning the trip todisengage it from the member upon failure of the retaining means, switcharms for separate circuits, tensionable means coupling the engagedmember to a switch arm of one circuit and flexible means coupling themember to a switch arm of another circuit, said tensionable couplingmeans being tensioned to move and draw the engaged member, upondisengagement of the trip from the latter, for shifting both switch armsto a predetermined position.

3. A circuit controlling device including a trip, a trip engaged member,means for retaining the said trip in engagement with the engaged memberunder certain conditions, said trip bein tensioned to disengage themember upon ailure of the retaining means, means for connecting themember with the operating arm of an electric switch, and a tensionableelement connected at one end to the said member and at its other to thearm of another switch, said element being tensioned to shift the engagedmember, when released from the trip, for operating the switches.

In testimony whereof I aflix my signature in presence of two witnesses.
